VersaClock® 5 Low Power Programmable Clock Generator

The 5P49V5908 is a programmable clock generator intended for high performance consumer, networking, industrial, computing, and data communications applications. Configurations may be stored in on-chip One-Time Programmable (OTP) memory or changed using I2C interface. This is IDTs fifth generation of programmable clock technology (VersaClock® 5). The frequencies are generated from a single reference clock or crystal.

Two select pins allow up to 4 different configurations to be programmed and accessible using processor GPIOs or bootstrapping. The different selections may be used for different operating modes (full function, partial function, partial power-down), regional standards (US, Japan, Europe) or system production margin testing. The device may be configured to use one of two I2C addresses to allow multiple devices to be used in a system. The device is packaged in a 48-pin 6mm x 6mm VFQFPN (NDG48), with an industrial operating temperature of -40 to +85°C.

Features

Generates up to four independent output frequencies with a total of 11 differential outputs and one reference LVCMOS output

Supports multiple differential output I/O standards:

Three universal outputs pairs with each configurable as one differential output pair (LVDS, LVPECL or regular HCSL) or two LVCMOS outputs. Frequency of each output pair can be individually programmed
